from the post:

i set up an openfire server instance on my debia wheezy server. I use a mysql server database to store the needed openfirestuff. If i use a 12 characters long passwort for the openfire database with numbers, capitals and smal letters and 1 ampersand symbol i get problems after a reboot.

So i start to set up openfire via the webconsole and define a database connection.

All went fine

If i reboot the debian server, openfire wont start. The error log tells me openfire cant access the database.

I set up openfire again over the webconsole with the same db connection password and all went fine again.

After a reboot, openfire wont start.

I modified the db passowrd to an easy word ( only 6 letters ).
I set up openfire again and after a reboot it still works.

It seems AES or blowfish encryption has problem with complicated db passwords.

UPDATE: In the last past nights i found out its only the " & " symbol who make this problem. Password with letters and digits only works.
